CUTTER CLEARANCE GAUGE.

Application led October 17, 19%3.

To @ZZ 'whom t may concern:

Be it known that I, WALTER F. SMITH, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in Cutter ClearanceGranges, of which the following is a specification.

rIhis invention relates to certain new and useful inprovements in cutterclearance gauges and the primary object thereof, is to provide a gaugeof this type which is adaptable for use with cutters of varyingdiameters and more specifically without the manipulation of screws ornuts or other fastenings. n

A. further object of the invention, is to provide a gauge which is ofsimple and economical construction, involving a minimum of parts thatcan be easily assembled and operated.

A still further object of the invention is to provide a gauge which hasa doubleended gauge point readily removable for substitution by anotherpoint having different angles for measuring different angles ofclearance, so as to make the gauge of wide use.

In the drawings:

Figure l, is a front elevation of the invention;

Figure 2, is a side edge elevation thereof; and

Figure 3, is a plan view of the slide.

In proceeding in accordance with the present invention a substantiallyand preferably integrally formed Y-shaped member is employed havingdivergent arms l and 2 and a central arm 8.

rIhe outer end portions of the arms l and 2 are preferably tapered andhave rounded points or free ends.

A guide 4 is attached to the central arm 3 and is composed of a platehaving a central channel 5, the latter facing the arm 3 and forming anopening in conjunction with the latter. Screws 6 secure the sides of theplate to the arm 3.

A slide 7 is movably received within the opening and extends beyond theouter ends ofthe arm 3 and the guide and beyond the points of junctureof the arms l and 2. The slide, 7 has its front and rear faces at itsends oppositely tapered or beveled and formed with angular gauge facesor edges Serial No. 669,164.

8 9 and 8-9 the latter faces or edges being of different angularrelation so as to afford a different clearance readings accordingly. Thetapered faces of the slide facilitate reading and with the contracted orcurved side portions thereof enable the slide to be more readilyintroduced into the ends of the opening conjointly formed by the guide 4and arm 3. The slide may be held in the guide opening by slight frictionso as to be capable of being readily slide to engage the cutter teeth.

In operation, the arms 1 and 2 are engaged with the cutter teeth and dueto the right-angular relation thereof, the device may be used withcutters of varying diameters. The slide is then moved to engage thepoints of the teeth and the angle of clearance of the latter thusdetermined.

By providing two or more of the slides, each of which may be used withthe same body of the gauge, the range of use of the gauge may be widenedaccordingly. It will also be noted that the arm 3 and the guide 4conjointly form a handle in set` ting and holding the gauge on thecutter teeth.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a cutter clearance gauge, a Y shapedbody, a fixed guide on the central arm of the body and cooperatingtherewith to form a handle, and a double ended slide in the guide havingits opposite side faces beveled and its ends formed with angular lyrelated gauge edges.

2. In a cutter clearance gauge, a substantially Y-shaped body formed toseat on the teeth of cutters, a guide on the central arm of the body,and a double-ended slide in the guide having angularly related gaugeedges on one end thereof movable to lie beyond the crotch of the body.

3. In a cutter clearance gauge, a body having right-angularly relatedarms formed to seat on the cutter teeth, and a slide carried by the bodyand disposed centrally between the arms and having angularly relatedgauge edges on one end thereof movable to lie beyond the crotch of thebody.

4. In a cutter clearance gauge, a V-shaped body formed to seat on theteeth of cutters, guide means having open ends fixedly related to theapex arm of the body, and a reversible slide gauge having each endthereof formed for insertion in the guide means and movable to have theinserted end lie beyond the crotch of the body, so as to 5 aline withthe space Centrally between the Witnesses:

legs of the body. S. N. BARRY,
